Updated: Jun 10, 2023

The CrossFit vocabulary can be quite confusing when you're starting out. You’ll be training in a ‘box’, doing ‘AMRAP’s’, and ‘TTB’ on a ‘rig’, all whilst hearing about the upcoming ‘open’ workouts and what ‘NOBULL’ merch people are going to buy.


To make things a little easier for you when starting out, we’ve listed some of the key terms/acronyms you will come to hear during our classes.
